Abstract

This research aims to identify common problems that occur in reliability and validity testing in research in the field of guidance and counselling. This research uses the Systematic Literature Review (SLR) method, which examines and reviews several articles related to common errors in reliability and validity testing. This research searched for several articles from various sources such as Google Scholar, Semantic Scholar, Springer, Routledge Taylor & Francis Group, Research Gate, and frontiersin.org within the past 5 years (2013-2023). The articles that have been searched are then analysed for common errors that appear related to reliability and validity testing, the results of this analysis are presented in tabular form and explained descriptively. The results of this study indicate that several studies in the field of counselling have 9 common errors that are often made in conducting quantitative research. These errors are: not including reliability and validity, not iterating and revising unreliable items, not conducting content validity analysis, not conducting construct validity analysis, mismatching the instrument with the characteristics of the item, the absence of judgment validity, not describing favourable and unfavourable items, limited samples on the instrument, and doubtful construct validity and the need for reliability testing on a wide scale. His research can be a study and reference material in conducting quantitative research, especially in the field of guidance and counselling.

Abstract

This research discusses the scale analysis of multicultural guidance instruments on students at Madrasah Aliyah Al Huda Cikalongwetan. West Bandung Regency. The following are the results of the Validity Test and Reliability Test of the research instrument scale regarding multicultural counseling. This Validity Test uses Pearson Correlation to determine the extent to which each item in the measurement instrument correlates with the total score. In the table presented, 67 items (X1 to X67) were tested. The Pearson Correlation value for each item ranges from 0.738 to 0.881, indicating that each item has a strong relationship with the total score. The significance value for all items was 0.000, which is well below the significance level of 0.05. This indicates that the correlations found do not occur by chance and are highly statistically significant. Based on the validity test results, all items (X1 to X67) were declared valid. This is indicated by the high Pearson Correlation Value and the very low significance value (0.000). Thus, the measurement instrument used can be considered valid to measure the intended construct. The Reliability Test results show that the measurement instrument consisting of 67 items has a Cronbach's Alpha value of 0.991. This value is very high and close to 1, which indicates that the instrument has excellent internal consistency. In other words, the items in this instrument consistently measure the same construct, so they can be relied upon to produce stable and accurate data. This high Cronbach's Alpha value provides confidence that the instrument can be used with confidence in research to measure the variable in question Keywords: Multicultural, Multicultural Counseling, Multicultural Guidance
